IMPROVEMENT IN vAPoR-BURNERS.

Specification forming part of Letters Patent No. 143,915, dated October 21, 1873 application liled Aprn 4, 1873.

To all whom it may concer-n:

Be it known that I, JOHN G. LOVE, of Philadelphia Pennsylvania, have invented Van Improved las or Vapor Burner, of which the following is a specification:

The objects of my invention are to preventv leakage around the valve-stem of a gas or vapor burner.; to insure a thorough vaporization of the oil; to render the burner less bulky than usual, and to reduce the cost of the same. I attain these objects by constructing the burner in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure l is an enlarged sectionalelevation, and Fig. 2 a sectional plan, of the burner on the line l 2, Fig. l.

1njXing-chamber,and playing upon and heating the supply-pipe, and a wing or metal plate, G, adjacentV thereto.

One of ,the greatest objections to burners of this class as heretofore constructed has been the difliculty of preventing leakage of oil between the casing B and valve-stem D-an objection which I have effectually overcome, as follows: I form the lower endl) of the casing into a tubular conical projection, the metal of which is so thin that it will yield to external pressure, and tightly embrace the valvestem; and this pressure I obtain by means of ra nut, H, adapted to an external thread on the casing, and having at its lower end a tubular conical proj ection, el, corresponding to that of the casing,`and fitting snugly-over the same,

so that,by simply raising the said nut, itshall.

be' causedto force the tubular projection b against the stem, thus forming an oil-tight joint. This part of my invention can, it will be evident, 'be applied afs a metallic packing to 'valve-stems generally, for the purpose of preventing leakage between the same and their casings.

The-mixing-chamber E is formed within a central tube, I, and surrounding concentric tube J this method of construction insuring ranged at or near the base of the. mixingchamber, instead of near the top of the same, as usual, so that the burner can be considerably reduced 'm length. The central tube I has Va long screw-thread, .'10, cut upon its lower end, which is made to serve the threefold purpose of securing the said tube to the casing B, of receiving the nut-valve K, by raising or lowering which the size of the air-openings h can be regulated, and of securing the upper portion of the burner to the said tube.

The wing Gr, upon which, as well as upon vthe supply-pipe, the y jets of flame from the apertures a are caused to play, is cast in one piece with the said pipe, as shown in Fig. 2,

`this effecting considerable economy of construction, and enabling the supply-pipe to be more thoroughly heated than if the said wing were separated from the same, as usual.

The lower portion of the supply-pipe is cut away, as shown at y, in order to permit the operation of the nut-valve, and to enable the said supply-pipe to be brought as closely as possible to the mixing-chamber.

I claim as my inventionl. The within-described metallic packing for valve-stems for gas-burners, consisting of a conical tubular projection, b, of the valve-casing, embracing the said stem, and arranged to be tightened upon the same by the corresponding conical projections cl of a nut, H, adapted to the threaded exterior of the casing.

2. The tube I, so combined with the other portions. of the burner that its single screwthread a* shall serve the threefold purpose of securing the same to the valve-casing, of receiving the nut-valve K, and of securing,` the In testimony whereof Ihave signed my name upper portion of the burner to the said tube, to this specification in the presence of two suball substantially as specified. scribing Witnesses.

3. The combination, substantially as de- JOHN C. LOVE. scribed, of the nut-valve K With the supply. Witnesses: pipe A, recessed at y to permit the operation THOMAS MCILVAIN, of the said'nut-valve. HUBERT HoWsoN.
